FURNACE-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 524,238, dated August'7, 1894. Application filed June 4, 1894. Serial No. 513,419. (Nomodel.)

To all whom it may concern:

Be it known that I, AUGUSTUS BEYER, a citizen of the United States,residing at New Philadelphia, in the county of Tuscarawas, State ofOhio, have invented certain new and useful ImprovementsinFurnace-Bottoms; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

' This invention relates generally to furnaces employed for heatingsheets of tin, steel, copper, 850., and it relates particularly to theconstruction of the bottom. Heretofore furnace bottoms have beenconstructed in such a manner that the heat did not have full and perfectaccess toall parts of the sheet or plate heated, and besidesthis theyfrequently soil and impair the quality of the sheet tin, as a clean,bright finish is one of the essential points in the manufacture of sheettin.

The object of my invention is therefore to which shall beindestructible, one that will permit the full and free circulation ofheat beneath the sheet; and one that can be readily kept clean, thusavoiding all danger of soiling the sheets during the process of heating.

With these various objects in view my invention consists essentially ina furnace bottom composed of a series of fire proof blocks or bricksarranged to form a complete bottom surface, each block or brick having apoint or protuberance projecting from the upper face of said block.

My invention consists also in certain details of construction andcombination of parts all of which will be fully described hereinafterand designated in the appended claims.

In the drawings, Figure 1 is a perspective view of a furnace bottomconstructed in accordance with my invention. 1 Fig. 2 is a transversesectional view. Fig. 3 is a detail view of one of the blocks or bricks.

In constructing a furnace embodying my invention I employ the side wallsA A and the surrounding border B all made of suit able fire proofbricks. Within the border B is arranged my novel furnace bottom 0 whichsupported upon a series of points the heat has a full and freecirculation above and below the same, and below it the flame and heatcan travel in all directions. The sheet is also prevented from cominginto oontact'with dirt or foreign substance, and should the bottombecome foul or impaired at any. point it can be readily cleaned orrepaired.

Metallic bottoms having a series of Studs have been used andalso bottomshaving longitudinal ribs, but these do not accomplish the objects of myinvention as the circulation of flame and heat is not complete andbesides this they are not composed of a series of fire proof blocks orbricks which can always be kept clean or fresh.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,is--

1. 'An improved furnace bottom formed of a series of fire proof blocksor bricks each of which has a protuberance projecting from the upperface of the same, substantially as shown and described.

2. An improved furnace bottom consisting of a series of blocks or brickseach having a projection upon the upper face, said blocks or bricksbeing arranged to form an unbroken surface substantially as shown anddescribed. In testimony whereof I affix my signature in presence of twowitnesses.
